In this study, predictive simulation and life cycle models were built for the hydrometallurgical recovery of gold and cobalt sulfate from prospective complex cobalt- and gold-bearing concentrates.
Although end-of-life (EOL) batteries are estimated to become a significant source of secondary cobalt in the future, recycled cobalt alone will not be nearly enough to satisfy the increasing demand during the next decade (Alves Dias et al. 2018 ).
In the case of the presumed cobalt grade (Co = 1.35%), 81.6% of Co was recovered in the High As case and 81.3% in the Low As case. It was also observed that the cobalt losses decreased significantly when the cobalt grade in the concentrate fed to the hydrometallurgical process increased.
Massive fluctuations in cobalt prices were seen between 2018 and 2019, due to which the GHGs allocated to cobalt sulfate were nearly twice as high in 2018 than in 2019: for the 2018 reference, the GWP of the High As case was 10.3, whereas the value was 6.0 kg CO 2 -eq for 2019.
The effect of the main cobalt minerals was so small that the other, so far unknown, process phenomena and the uncertainty in the recovery rates had a more profound effect on the footprint of the process than the main cobalt minerals.
Dai et al. ( 2018) presented the life cycle inventory (LCI) data for cobalt and cobalt chemicals production at Chinese refineries from DRC’s Cu-Co ores. Cobalt was also one of the metals that was investigated on the study by Nuss and Eckelman ( 2014) based on the data from ecoinvent 2.2 database.
